Description
In the limit of QCD where heavy quark masses go to infinity new symmetries appear which enable one to predict the hadronic form factors that occur in the semileptonic decays anti B → Deanti νe, anti B → D*anti νe and Λb → Λceanti νe. These results may eventually improve our ability to extract the weak mixing angles from experimental data on anti B and Λb decay. (orig.)
